This set of 25 brad point bits are made from M2 high speed steel and are the finest wood drill bits that we have ever offered. They feature two lips on the perimeter, that finely score the circumference of the hole, prior to the chipping bevels removing the stock. This results in minimal fibre pull and tearing of the wood leaving extremely clean holes in hardwoods, softwoods and composite woods.
The bits are back tapered from the cutting edge to minimise friction and prevent binding and have been fully ground to give precise concentricity to ensure a highly accurate hole. The deep flutes are polished to allow fast chip clearance, preventing the build up of swarf in the flutes, resulting in smooth, scorch-free side walls. M2 high speed steel is extremely hard wearing and retains its hardness over prolonged use, resulting in a bit that will not deform and which will always keep the same cutting geometry over its lifetime. After hardening these bits are tempered to reduce brittleness and increase ductility and toughness, staying sharp 10 times longer than carbon steel brad point bits.
This set contains 25 metric bits ranging from 1mm to 13mm in 0.5mm increments 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm, 1.5mm, 11mm, 11.5mm, 12mm, 12.5mm and 13mm and is supplied in a bespoke wooden presentation box. The bits are certified to ensure the dimensional accuracy of the hole. ©
